1.  INSTALL NOTES

    1.1 Entering New Activation Codes
    
        If upgrading from 5.1.x or below, new activation codes must be
        entered. GB-OS version 5.2.5 is available at no charge to
        customers with a GTA support contract or annual maintenance
        agreement. Other users should contact their local Authorized GTA 
        Channel Partner or email sales@gta.com for information and pricing 
        of upgrade options.

        
    1.2 Upgrade Notes   
        
        1.2.1 Re-sizing Slices and Runtime Upgrades
              
              In order to support the new features in GB-OS 5.2 and above, 
              some firewalls may require partition re-sizing during the 
              upgrade process. Upon re-sizing, both runtime slices will have 
              GB-OS 5.2.5, and firewall administrators WILL NOT be able to 
              revert to previous runtimes via the Console or Web interface.
              
              GTA strongly recommends backing up current firewall 
              configurations PRIOR to upgrading.

              Firewalls requiring re-sized partitions will take approximately 
              5-8 minutes to reboot and fully update once the runtime has 
              been applied. DO NOT switch off or reboot the firewall during 
              this process.

        
        1.2.2 Error Messages Upon Initial Reboot
    
              Upon rebooting after successful installation, the GTA
              Firewall UTM Appliance may display errors when accessed
              using the Web interface.  This is expected, these errors are
              generated because the browser's cache is trying to access
              files and locations that no longer apply. Click OK to any
              displayed errors and refresh the browser window to access
              GB-OS 5.2.3. If the error messages persist, clear your
              browser's cache.
            

    1.3 SSL Certificate Replacement

        GB-OS version 5.2.5 will install a new default security/SSL
        certificate. Some browsers, including Netscape and Mozilla,
        will not recognize the new certificate if the original has
        never been replaced. If you are unable to log on to the
        firewall after upgrading, delete the browser's cached security
        certificate, then close and restart your browser before
        reattempting remote access to your firewall.
    
    
    1.4 Mail Sentinel Anti-Virus 
    
        Since the release of GB-OS version 5.1.2, Mail Sentinel Anti-Virus is 
        no longer available as a separate subscription option. Mail Sentinel 
        Anti-Virus is included as a standard feature with valid support 
        contracts.
